Weba) the rows/columns are linearly independent then the kernel is {0}. b) a=b=c=d=0 then the kernel is the entire vector space. c) The rows are linearly dependent, say [c,d] is a multiple of [a,b]. Then the kernel consists of all vectors [x,y] such that ax+by = 0. Clearly this subspace is generated by [-b,a]. Okay, thanks.
